III — SPECIFICATIONS (STANDARD)
The following specifications apply to all standard (no suf-
fix) HSF-PFC 50 Watt Series models. Table 1 lists the
specifications that differ for each model. Common specifi-
cations that apply to all standard models are listed in the
paragraphs following Table 1. Other models are also avail-
able; consult your Kepco representative for their specifica-
tions.
NOTE

(1) Derates same as Output Power.
(2) Current Limit is rectangular. After the overload is removed,
output is automatically restored.
(3) See power derating curve, Figure .
(4) Peak current and thermal protection applicable to 24V model only.
See Figure 1 for peak power requirements.
(5) Ripple and noise will be approximately 1.5 times higher when
operating temperature range is between –10°C to 0°C.
